BUILDING-BLOCK.

To all whom t may concern.'

Be it known that I, ARTHUR IVHITE, a citizen of the United States, and resident of Sheboygan Falls, in the county of Sheboygan and State of l/Visconsin, have invented new and useful Improvements in Building-Blocks, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates. Vto improvements in building blocks formed of cementitious material. Y

It is one of the objects of the present invention to provide a building block of the maximum strength with the minimum amount of material, and which is of such shape as to form a wall of great strength.

A further object of the invention is to provide a building block soshaped that a wall constructed of a number of similar shaped blocks will have the appearance of being formed of blocks of different sizes thereby relieving the monotony of walls formed in the ordinary manner.

A further object of the invention is to provide buiding blocks which interlock both endwise and sidewise with each other when a wall is built therefrom.

A further object of the invention is to provide building blocks with air spaces so arranged that in a wall constructed therefrom an imaginary line extended through the wall either transversely or obliquely would intersect one or more of the'said air spaces.

A further object of the invention is to provide building blocks in which the interlocking means also serves to positively aline the blocks vertically in a manner to break the joints in a line exactly in the center of the adjacent upper and lower blocks.

A further object of the invention is to provide a building block or slab which is also adapted to be used in building floors, roofs, ceilings or side walls of a building.

With the above and other objects in view, the invention consists of the improved build` ing block and its parts and combinations as set forth in the claims, and all equivalents thereof:

In the accompanying drawing in which the same reference characters indicate the same parts in all of the views: Figure 1 is a top view of several of the blocks assembled together. Fig. 2 is an inverted bottom view Specicaton of Letters Patent.

thereof; Fig-3 is a transverse sectional view of the blockstaken on line 3-8 yof F ig. l; Fig. 4 is a vertical longitudinalsectional view of several of the building blocks .taken on line 4-4 of Fig. 1; Fig. 5 is a side view of a portion of a wall constructed of the `1 improved building blocks; and Fig. 6 is a perspective view of a. floor and a partition wall formed of the improved blocks.

Referring to the drawing the numeral 8 indicates the improved building block or slab which is formed of a cementitious material and preferably approximates a T- shape andv is adapted to lie upon its side edges when assembled in a vertically extending wall, the long face 9 and the short face 10 forming the outer and inner' surfaces of the'wall. Each block is formed with a body portion 11, having' a stem 12 'projecting Vmedially, laterallyy from one vertical wall of the block to form the short face 10 of the block. The stem 12 projects from the body portion one half the total width of the block and is of a length one half the total length of the block to provide for the blocks overlapping one another lengthwise, so that when the blocks are arranged with the long and short faces of adjacent blocksextending to the opposite surfaces of the wall they will form a smooth even exterior wall surface of the width of one block. As the stem is of a length one half the total length of the block, the end portions 13 of the body portion 11 are each necessarily one half the length of the stem or one quarter the total length of the block so that when assembled together each end` of the block ywill be overlapped by one quarter of the length ofthe adjacent end block with the end portions of each block abutting against Athe stem portions of the adjacent blocks.

`The lower medial portion of each block f isl provided with a rectangular loc-king recess or pocket 14 to accommodatev the ribs 15 projecting from the upper surfaces of the blocks. upper surface ofthe outer ends and on the stem portions of each block and when two of the blocks are assembled together the ribs on adjacent end portions of the two blocks will combine. to form a rectangular projection or rib 1,6 which will extend into and lit the locking recess or pocket 14 ofv a block placed on top of the adjacent blocks, the upper block being positioned to break the joint of the adjacent blocks below. This These ribs are formed onv the;l

constructionprovides a strong longitudinal and lateral interlocking bond for the blocks and also serves to aline the blocks with relation to each other. The side edges 17 of the ribs and the side walls 18 of the recessed portions of the blocks are beveled to permit the ribs to easily enter the recesses.

Each block is formed with three vertically extending angular air spaces or fiues 19 which areseparated by an angular web portion'20 forming part of the blocks. The web portions 2O are Y-shaped in form with the stems 19 connected to the stem portions 12 and the diverging arms 19 connected to the body portions 11. The angularity of the web provides for the iiues side-lapping each other laterally to eliminate a direct straight line connection either transversely or obliquely through the wall from the front to the rear portions of the blocks. The air spaces or liues are also formed with extension flues 21 which project into the end portions 13 of the blocks and side-lap the extension flues of adj acentblocks. This web construction also serves to strengthen the side walls of the block.

The inner side faces of the end portions of the blocks are provided with recesses 22 which vregister with each other when the blocks are assembled in a wall to form air spaces 23 interposed between the extension air spaces 21. v s

The inner corners 2A of the end portions of the blocks are beveled to provide space for cementitious material (not shown) when it is desired to use a binder for the blocks.

In buildings where the blocks or slabs are used in constructing Hoors, ceilings, roofs, or partitions the blocks are elongated to a considerable extent as shown in Fig. G over the other blocks shown and in some cases the locking tongues and recesses are formed on the ends of the blocks as indicated by the numerals 16 and 14 or are omitted entirely from the blocks when desired.

While the term block is used in the claims it is to be understood that the word contemplates a block, slabtile.or other form which may be used and is to be so interpreted in the specification and claims.

From the foregoing description it will be seen that the improved block provides for a wall, floor, ceiling or partition construction which is bonded together both laterally and longitudinally and that the inner portion of a wall formed of the blocks lis insulated Vfrom the outer portion by air spaces or flues which side-lap each other and prevent direct radiation or transmission of heat, cold or dampness. It will also be seen that the Copies of this patent may be obtained for materiallyv thereof, one of the ribs of the block being of a shape to combine with the rib of an endwise adjacent sidelapped block and form a combined rib corresponding I approximately to the shape of the locking recess of the adjacent block and to enter the locking recess of a block covering the joint of the endwise adjacent blocks in staggering relation to lock the three blocks together.

2. A building block, comprising a body portion having a stem projecting medially from one vertical side thereof and having a pocket formed medially in one of the horizontal sides of the body portion and stem, and with spaced tongues projecting from the opposite horizontal side of said body portion and stein adjacent to the end portions thereof, said tongues each being of a form approximately corresponding to the shape of one-half portion of the pocket,

said body portion and stem also provided with side lapping air spaces extending vertically through the stem and the body portion of the block.

3. A building block, comprising a body portion having a stem projecting medially from one vertical side thereof and provided with an air space divided by a medial partition or reinforcing wall having forked end portions which extend divergingly from one of the wall portions to the opposite side wall portion to form overlapping spaces, the

longitudinally extending outer spaces eX- tending beyond the junction of the stem portion with the body portion of the block and beyond the ends of side-lapped similarv blocks, whereby the said longitudinal spaces overlap the joints formed between said sidelapped adjacent blocks when the block forms part of a wall of similar blocks.

ln testimony whereof, 1 affix my signature, in presence of two witnesses.
